ISTANBUL, Aug 27 (Reuters) - The Turkish lira slid 3 percent against the dollar on Monday as local markets resumed trading after a week-long holiday and investors focused again on a bitter dispute between Ankara and Washington over an American pastor being tried in Turkey.

With the dollar stronger globally, the lira weakened as far as 6.19 from a close of 6.00 on Friday. It has lost nearly 39 percent of its value against the U.S. currency this year. (Reporting by Daren Butler; Editing by David Dolan)
